Vir 10-Gigabis Ethernet, watter van die volgende tipes kabel sal die beste gebruik word vir afstande van meer as 20 km? For 10-Gigabit Ethernet, which of the following types of cable will be best suited for distances of more than 20km? (2) 10GBase-SR, 10GBase-LR, 10GBase-ER, 10GBase-CX4, 10GBase-T 10GBase-ER Vraag 2: “Data link” Protokolle / Question 2: Data Link Protocols [13] Beskou die volgende geval en beantwoord die vrae wat daarop volg: Observe the following case and answer the questions that follow: ‘n Maatskappy word genader om ‘n netwerk by ‘n kantoorblok op te stel. Die kantoorblok is redelik oud en baie van die elektriese kabels veroorsaak elektromagnetiese interferensie in die gebou. Die hardeware is reeds opgestel, maar weens die maatskappy se vereistes moet al die netwerkprogramering met die hand gedoen word. Die eerste fase van die opstel van die “data link” dienste fokus op die kommunikasie protokolle wat gebruik moet word. A company has been approached to set up a network at an office building. The building is rather old and a fair number of the electrical cables cause electromagnetic interference in the building. The hardware has already been installed and set up, but due to the company regulations all of the network programming has to be done by hand. The first phase in setting up the data link services focuses on the communication protocol that has to be used.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
